  • Patent number: 5566027
    Abstract: A resin layer having an improved durability may be obtained by curing a photocurable resin composition, including: (A) a polyfunctional urethane-modified polyester (meth)acrylate comprising a polyester oligomer and a plurality of (meth)acryloyl groups bonded to the polyester oligomer via a urethane group, and having a number-average molecular weight of at least 700, (B) a polyfunctional (meth)acrylate having a number-average molecular weight of less than 700, (C) a monofunctional (meth)acrylate, and (D) a photopolymerization initiator. The cured resin layer shows a Young's modulus which shows a small temperature-dependence, and reduces the possibility of peeling of an optional overcoating layer formed thereon.

  • Patent number: 4236827
    Abstract: An opto-acoustic gas analyzer has a black body light source, a chopper in the path of the light emitted from the light source for intermittently intercepting the light from the light source, a positive interference filter in the path of the light for filtering out light other than the wavelengths of light absorbed by the gas being analyzed, and an opto-acoustic detector which receives the filtered light and through which the gas to be analyzed is passed. A pressure change detector provided is provided in the opto-acoustic detector for detecting pressure changes in the gas and producing an electric signal corresponding such changes.

  • Patent number: 4234255
    Abstract: A combined motor and rotational cell for use in an apparatus for measuring components in a gas colorimeter, smoke meter, etc. by utilizing light absorption or fluorescence. The combined motor and rotational cell has a motor with a plurality of magnetic poles around the periphery of thereof, at least one diametrically extending partition wall extending across the hollow interior for defining at least two compartments in the rotor, and optically transparent windows on the outside of the motor closing the compartments. A plate-shaped chopper is provided on one side of the rotor having a plurality of apertures therein equidistantly spaced around the chopper. A casing surrounds the rotor and supports the rotor shaft in bearings and has a plurality of coils around the inside of the peripheral wall opposed to the magnetic poles on the rotor. Apertures are provided in the opposite end walls of the casing aligned with the compartments in the rotor for passing light through the casing and the rotor.
